Tianshi Zhong set a new world record in the women's time trial before compatriot Jinjie Gong won gold on a day to remember for China at the UCI Track Cycling World Cup in Mexico.

Zhong kicked off the second day of action at the new velodrome in Aguascalientes in spectacular fashion, setting a time of 10.573 for the 200 metres flying start to best the previous record of 10.643 set by Germany’s Miriam Welte in June last year.

The Chinese rider's time is yet to be ratified. She went on to finish fifth in the final as her team-mate Gong claimed victory.

Meanwhile, Katarzyna Pawlowska won the individual pursuit to take her gold tally to two following victory in the points race on day one. The Pole is the new title holder in both disciplines.

Russia's Artur Ershov won the men's omnium after claiming victory in the individual pursuit, ahead of Vivien Brisse of France and Czech rider Ondrej Rybin, who won the kilometre time trial.

Dutchman Matthijs Buchli rounded off the night's action with victory in the men's keirin to take the World Cup title ahead of Germany’s Stefan Boetticher, who won in Glasgow.

Fabian Puerta could not match his opening round feats in Cali, when he won the race, and the Colombian came in third.

One final day of action remains in Mexico, with the final of the men’s Madison, men’s sprint, women’s omnium and women’s keirin all on the agenda.
